“Why would “asymptomatics” go to an urgent care?”
They wouldn’t, but all the people they infected would generate some nice hotspots. Best data we have says 45% of all cases are symptomatic.
With an R0 north of 2, every one of your asymptomatics is going to infect 2+ people, one of whom will display symptoms. After infecting 2+ other people. And so on.
They don’t exist, or the mechanics of this disease are so bizarre we might as well throw in the towel.
Maybe if you are not sick, but a carrier, it just waits until you are sick with something else to activate. Wouldn’t that suck? (That’s a horror story, not a hypothesis, for the record.)
But asymptomatics are not going to be all that contagious/transmitting, (I’m sure R0 pretty low), because they wouldn’t be coughing and sneezing much, by definition.
We should also consider fomites in the thought experiment.
